Montana is America’s premier fly fishing destination — home to legendary rivers like the Madison, Yellowstone, Big Hole, Missouri, and Bighorn. But Montana’s licensing system is unique: you need three separate components to fish legally. The total comes to $31 for residents and $117.50 for non-residents per season.
Big change for 2026: As of March 1, 2026, Montana fishing licenses are available exclusively online — they are no longer sold in-person at fly shops, sporting goods stores, or convenience stores. Plan ahead and purchase before your trip.

The Three Components You Need
Montana requires all three of these items to fish legally:
| # | Component | Resident | Non-Resident | Purpose |
|---|---|---|---|---|
| 1 | Conservation License | $8.00 | $10.00 | Prerequisite for all outdoor licenses |
| 2 | AIS Prevention Pass (AISPP) | $2.00 | $7.50 | Aquatic invasive species prevention |
| 3 | Fishing License | $21.00 | $100.00 | Permission to fish |
| Total | $31.00 | $117.50 |
No additional stamps required. Montana does not have a trout stamp — your fishing license covers all species including rainbow, brown, cutthroat, and brook trout, plus mountain whitefish, walleye, bass, pike, perch, and more.

Non-Resident Short-Term Options
Montana offers pre-packaged short-term bundles that include all three components:
| Duration | Total Cost (16+) | Total Cost (12–15) | Per-Day Cost (16+) |
|---|---|---|---|
| 1-Day Package | $31.50 | $24.00 | $31.50/day |
| 5-Day Package | $73.50 | $66.00 | $14.70/day |
| Full Season | $117.50 | — | Varies |
When Is Each Option Best?
| Trip Length | Best Option | Cost | Notes |
|---|---|---|---|
| Single day | 1-Day Package | $31.50 | |
| 2–4 days | Multiple 1-Day or 5-Day | Varies | 5-Day often better at 3+ days |
| 5–7 days | 5-Day Package | $73.50 | Best per-day value for trips |
| 8+ days or multiple trips | Full Season | $117.50 | Breaks even vs. 5-Day at ~8 days |
Break-even: If you plan to fish Montana for more than ~8 days in a season, the full season license ($117.50) is cheaper than buying two 5-day packages ($147). For a single week-long trip, the 5-day is your best bet.

| Resident senior (64) | Reduced Conservation + AISPP + Reduced Fishing | $16.50 |
| Resident youth (14) | Reduced Conservation + Reduced Fishing | $14.50 (AISPP exempt if 15 or under) |

How Montana Compares to Western States
| State | Resident Annual | Non-Resident Annual | Trout Stamp | NR Total |
|---|---|---|---|---|
| Montana | $31.00 | $117.50 | None | $117.50 |
| Colorado | $36.08 | $97.08 | None | $97.08 |
| Idaho | $30.50 | $98.25 | $16.75 | $115.00 |
| Wyoming | $27.00 | $102.00 | None | $102.00 |
| Oregon | $44.00 | $98.50 | Combined Tag | ~$125+ |
| Washington | $37.95 | ~$84.00 | None | ~$84.00 |
Analysis: Montana’s resident rate ($31) is competitive with neighbors. However, the NR annual ($117.50) is the highest in the Rocky Mountain region — reflecting the extraordinary demand for Montana fishing access from out-of-state anglers. Idaho with its trout stamp ($115 total) is the only state that comes close.
Understanding the AIS Prevention Pass
Montana’s Aquatic Invasive Species Prevention Pass (AISPP) is unique among western states:
| Aspect | Details |
|---|---|
| Cost | $2.00 resident / $7.50 non-resident |
| Required for | All anglers 16+ (youth 15 and under exempt) |
| Why it exists | Funds Montana’s fight against quagga/zebra mussels and other invasive species |
| What it funds | Watercraft inspection stations at highways, decontamination programs, monitoring |
| Validity | One license year (March 1 – February 28) |
| Exemptions | Youth 15 and under |
Why this matters: Quagga and zebra mussels have devastated water systems in the Great Lakes and Southwest. Montana is one of the last major western fishing states without established mussel populations, and the AISPP funds the inspection and decontamination programs that keep it that way.
⚠️ Online-Only Purchasing (New for 2026)
As of March 1, 2026, Montana fishing licenses are available exclusively online:
| What Changed | Details |
|---|---|
| Old system | Buy at fly shops, sporting goods stores, convenience stores, Walmart |
| New system | Online only at fwp.mt.gov |
| Why | FWP transitioning to streamlined digital system |
| Impact | Plan ahead — buy before you arrive; no last-minute in-person purchases |
Critical for visiting anglers: If you’re driving to Montana for a fishing trip, buy your license online before you leave home. You can no longer stop at a fly shop in Bozeman, Missoula, or West Yellowstone to buy a license. Purchase at fwp.mt.gov and print or save your license digitally.
Who Fishes Free in Montana?
| Group | Details |
|---|---|
| Children under 12 | No license, conservation, or AISPP needed |
| Free Fishing Day | One day per year (typically in June) |
Montana has one of the most restrictive exemption policies in the country. There is no complete senior exemption — seniors 62+ get a reduced rate ($16.50 total) but not free. There is no disability exemption. No military exemption from fees. Montana’s conservation funding model relies on broad license participation.
